Given numbers are 243, 637, 861, 541

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(243, 637) = 154791

GCD(243, 637) = ( 243 x 637 ) / 154791

= 243 / 637

= 243

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 541) = 541

GCD(1, 541) = ( 1 x 541 ) / 541

= 1 / 541

= 1

So, Greatest Common Divisor of 243, 637, 861, 541 is 1
